The Moisture Mechanism That Causes Asphalt Stripping in Asphaltic Pavement Mixtures
The purpose of this study is to determine the mechanism that causes pavement failures in the form of stripping of the asphalt binder from aggregate. The asphalt binders, aggregates, bituminous mixtures and pavement samples from three pavements in Idaho were used in the investigation. A series of dynamic compressive fatigue tests were made on water staturated specimens. It was found that the type of mixture was not important when containing over 8-9% air voids but when air voids were below this value the fatigue life was effected by the mixture type. Test results show that both the percentage of air voids and the stress level must be known to estimate fatigue life of a paving mixture saturated in water. BPR Abstract)
